My minibook N4100 does not start anymore. when starting the fan starts but I have a black screen. Impossible to boot on a USB flash drive, everything is blocked. No Chuwi logo. I completely turned off the machine and restarted it.

This problem occurs when I modified the operating system in Linux in the bios.

Does this mean that incorrect bios settings can make the minibook unusable?
If this is the case, it is incomprehensible, by changing the declaration of the operating system, I have never known such a thing.

I have the same problem on a lapbook Pro. Also after a change in the BIOS. I wrote to service@chuwi.com a few days ago. THEY DO NOT ANSWER. The whole party should have a problem, measures must be taken.

On 16/12/2019 I received an e-mail sent by chuwi to everybody via the indiegogo platform with subject “Update #26 from MiniBook-Mobile Workstation In Your Hand”.
In this email they published a small FAQ and all the download links to the firmware and bios download files.
In the email FAQ they did explicitly write:
“Q4: The cooling fan is too noisy.
A4: Reinstall the BIOS”

Since the annoying fan on my unit was constantly on today I flashed as instructed the right BIOS and EC files for my N4100 minibook.

And now the laptop turns on to a black screen, no chuwi logo anymore, just the led and the keyboard backlight light up.

Since Chuwi did not provide any recovery procedure or dual bios (at least i dont know about it), you need to send the laptop to the service or buy a programmer+stepdown adapter and manually flash the old version of EC and bios.

Thanks for the reply, I’ve looked at that file and it’s 132Kb and the actual EC chip is 1Mb. The 132Kb file doesn’t work by flashing with a hardware flasher and it’s not simply padded for 1Mb so we’re stuck without an actual dump. We can’t flash that file because out 4100 minibooks do not boot into UEFI (bios) without a worked EC. Catch 22.
